ID-based tripartite key agreement with signaturesAugust 9th, 2020
FiledAugust 9th, 2020Abstract : This paper proposes a new identity based tripartite key agreement protocol which is more efficient than the existing ID-based tripartite protocol. This protocol is based on the Joux's protocol for key agreement, and introduces signature along with key agreement to overcome man-in-the-middle attacks and to provide authentication. The new protocol resists existential forgeries against adaptively chosen message attacks under the random oracle model.
